line 1. INTRODUCTION Wireless ad hoc networks have emerged to support applications‚ in which it is required/desired to have wireless variety of devices without relying on communications among a any infrastructure or central management. In ad hoc networks‚ wireless devices‚ simply called nodes‚ have limited transmission range. Therefore‚ each node can directly communicate with only those within its transmission range (i.e.‚ its neighbours) and requires other nodes to act as routers in

What is WiTricity ? -WiTricity‚ stands for wireless electricity‚ is a term coined initially by Dave Gerding in 2005 and used by a MIT research team led by prof. Marin Soljačić in 2007‚ to describe the ability to provide electricity to remote objects without wires (wireless power transfer). This could be useful to power consumer and industrial electronics like cell phones‚ laptops‚ etc. -WiTricity‚ a portmanteau for "wireless electricity"‚ is a trademark of WiTricity corporation referring to their
